Struthiomimus altus

Struthiomimus altus

The very ostrich-like body of this fleet-footed dinosaur suggests it led a similar lifestyle to what we can observe in extant ratites. Its long stride could have propelled it to speeds as high as 80 kph (50 mph). Its long, stiff tail could have helped make steering at high velocity more manageable. Though Struthiomimus has three fingers on each hand, two of them appear to have been attached in a way that prevented independent movement. Struthiomimus, the “ostrich mimic”, lacked teeth and had a small head compared to its body size.
